COKE-OVEN.

SPEOFIOATION forming part of Letters Patent No. 705,446, dated July 22, 1902.l

Application iiled February 6,'1902. Serial No.92,849. (No model.)

To ctZZ whom it may concern:

Be it known that 1,'MATH'EW E. ROTHBERG,

a citizen of the United States,and a resident of Lebanon, in the county of Lebanon and State of Pennsylvania, have made a certain new and useful Invention in Coke-Ovens and I I declare the following to be a full, clear, and

exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the'invention, reference being had 'to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The invention relates to horizontal open-end coke-ovens; and it consists in the novel construction 'and combinations ofparts, as hereinafter set forth.

The object of the invention is to provide such ovens with a system of heating or combustion flues between and underneath the coking-chamberswhereby it is designed to secure great heat economy, strength of construction, and rapidityof cokingaction. ,1

The invention is also designed to provide eiicien cy for regulating and distributing the heat in the different liues, thereby aifording means for heating the different parts of the oven-wall at will', forre'covering the heat from the Waste gases to the air-supply, and

for utilizing' the deadl heatin the top of the' i'iues for heating the air before it Ventersv into -the combustion-fines.v f

The nature of this improvement will be best understood in connection with the drawings,illustrating the same,-in which- Figure l is a longitudinal section through a main system of heating or combustion fiues, the section being taken on the line I-I H, Figs. 3 and 4. Fig. 2 is a longitudinal section taken on the line J J, Fig. 3. Fig. 3 shows vertical sectional views taken on the lines A kA, B B, C C, and D D, Fig. l, and also shows an end view of oven and flue. Fig. 4 shows sections taken on 'the lines E E, F F, and G G, Figfl, as well as a top view of the oven and flue.

The letter A indicates a suitable foundation for the ovens B', this foundation containing a series of passages H', serving, respectively, as cooling-hues for the ovens above them. The ovens are built in adjacent pairs,

as indicated, and the interval or longitudinal Wall in thev structure between the cokingchambersris hollow, its chambered portion or cavity being divided into two compartments by a verticahtransverse Wall D. Each of these compartments is traversed by a series of horizontal longitudinal combustion or heating fluesBformed by longitudinal deflecting-partitions b, one above another, such flues communicating at their ends and the series communicating. below with a series of short connected horizontal transverse lines C', the latter flues extending under the ovenchamber. The lowerflue B3 communicates With iiues C by means of angular flues or passages B4. The lues C are formed by short deflecting transverse partitions c. To the uppermost ofthe series of liuesBs extends a -pipeH3 fromithe fuel-gas main G2, and the heated. gases. pass through the flues B3, B4, and Cv to the iiue C2 in the foundation, Where- .from they pass out by means ofa suitable stack. .In the draft iiue C2 is located an air-pipe D2, in which air is heated by the Waste gases passing to the stack, and this heated air is conveyed to the main air-pipe D which communicates with hot-air flues F2 Fformed inthe structure above the level Vof the tops of the ovens by means of a pipe F6, which is provided with a regulating-valve E2.4 The pipe H3 fromthe fuel-gas main is also provided with a regulating-valve at G3. The fluevF2 is provided with a longitudinal deecting-partition ct, whereby the heated air is caused to traverse the structure back and forth to the passage or flue E3, which extends vertically inthe fronts of the structure and communicates with the flues B3 by means of openings E4 and with the outer air by means of openings F4. The openings E4 and F4 should be provided with dampers to regulate the amount of air admitted to the iues B3. Dampers are provided at DG to regulate the passage of the gases to the iiu'es O2. By means of these combustion-dues and air-lines the oven-chambers are yencompassed in such Wise that their heating can be quickly accomplished and easily regulated to suit the work. The lues F2 in the top of the structure serve to recover the dead heat and provide for its utilization in the air-supply.

Having described this invention, what I IOO claim, and desire to secure by Letters Patent, is

1. In adjacent coking-ovens, a hollow longitudiual wall separating the oven-chambers, and longitudinal deiecting-partitions forming heating or combustion flues in the cavity or chamber of said wall, and a vertical hot-air flue at the outer ends of said combustion-lines, the inner Wall of which air-flue is pierced for passage of air to the combustionliues, substantially as specified.

2. In adjacent coking-ovens, a hollow longitudinal wall, separating the oven-chambers, longitudinal deflecting-partitions forming heating or combustion ues in the cavity or chamber of said wall, said ovens having a chamber thereunder, and a series of transverse defiecting-partitions in said chamber forming reverting-fines leading to the draftflue, and connecting with said longitudinal fines, substantially as specified.

3. In adjacent coking-ovens, a hollow longitudinal wall separating the oven-chambers, longitudinal deflectingpartitions forming heating or combustion lines in the cavity or chamber of said wall, a hot-air flue located above the oven, and communicating with a vertical flue at the end of the combustionflues, said vertical flue having communication with the combustion-fines, and said hotair tlue connecting with a hot-air pipe located in the draft-fine, substantially as specified.

4. In adjacent coking-ovens, a hollow longitudinal wall separating the oven-chambers, longitudinal defiecting-partitions forming heating or combustion fines in the cavity or chamber of said wall, a hot-air fiue located above the oven-chambers, and communicating with said combustion-nues, and with a hot-air pipe located in the draft-flue, substantially as specified.

5. The adjacent coking-ovens, having the vertically-separated horizontal longitudinal fille-compartments between the oven-chambers, communicating with transverse fines underneath said chambers, the deflecting airiiue above the level of the oven-chambers, and vertical air-fines communicating with said detlecting air-fines and the horizontal tine-compartments, substantially as specified.

6. In a coking-oven, the combination with adjacent open-end coking-chambers, of a hollow intervening longitudinal Wall, a vertical central transverse partition in said wall, horizontal longitudinal defiectingiues in the compartments formed by said partition, transverse fiues underneath the coking-chambers leading to the draft-fine, deiiecting airiiues in the upper part of the structure, vertical air-iues in the front of the same, means of supplying fuel and air, and devices for regulating the supply of fuel and of air, and for regulating the draft, substantially as specified.

In testimony whereof I aix my signature in presence of two witnesses.
